Russia's President Dmitry Medvedev will sign bilateral business deals with his Czech hosts, according to AP. Medvedev will also open an exhibition of Kremlin's priceless treasures on Thursday. Also on the agenda of the talks with President Vaclav Klaus and Prime Minister Petr Necas is the thorny issue of U.S. and NATO missile defense plans as well a Russian bid to build two more reactors at a Czech nuclear plant. Medvedev threatened last month to deploy missiles to target U.S. missile shield sites in Europe if Russian concerns are not met.
